Description
Technical field
The present invention relates to a kind of transparent keycap, its manufacturing method and comprising the luminous button of the transparent keycap, and it is special
It is not about comprising cooperation indicator lamp signal and manufacturing yield height, the transparent keycap of the strong light obstructing member of engaging force, its manufacturing method
And the luminous button comprising the transparent keycap.
Background technology
Illuminated keyboard has been common on the market input peripheral device.In the existing luminous button for illuminated keyboard,
The transmission region of definition character/symbol is had on most of keycaps, can be also defined on several keycaps indicator lamp signal (for example,
Capital and small letter locks open instruction cresset etc.) transmission region.
If having definition character/symbol transmission region different from two kinds of indicator lamp signal on the keycap of luminous button, shines and press
Key then needs two light sources of installing.Two light sources correspond to a kind of transmission region respectively, and it is right that the light emitted is each passed through its institute
The transmission region answered, and another transmission region should not be incident upon.This kind of luminous button all needs the design of shading, to cover two
The light that a light source is emitted will not allow the light that two light sources are emitted to pass through not corresponding transmission region.
About the luminous button with definition character/symbol transmission region different from two kinds of indicator lamp signal on above-mentioned keycap
Prior art please refers to TaiWan, China patent announcement M381117.M381117 patent disclosures are a kind of with low scattering light
Keyboard, circuit board are equipped with luminescence component at the specific keycap of correspondence (by taking Caps lock keys as an example), and in specific keycap
Supporting mechanism and elastic component are respectively set between substrate base, makes specific keycap that can do upper and lower movement relative to substrate base.
Specific keycap corresponds to luminescence component and is equipped with transmittance section, and transmittance section is provide with made by light-transmitting materials, and in luminescence component periphery
Light shield.Light shield is by having elasticity and opaque material is made (for example, rubber), and light shield is substantially in coniform and by circuit board
It extends upwardly to close at transmittance section.Light shield, which corresponds to transmittance section, has opening.Portion of the size of the opening about with transmittance section minimum
Split-phase is same, and the light that luminescence component is sent out is made only to be appeared by the opening and project specific keycap through transmittance section.
The light shield of M381117 patent disclosures need to additionally mold manufacture, and make the assembling of button complicated.Light shield with it is specific
Keycap and the fastness of substrate plate engagement still have improvement space.
M381117 patents are also disclosed replaces light shield using shading piece.Shading piece is made of opaque material, and sets
Bottom surface in transmittance section.Shading piece, which corresponds to transmittance section, has opening, the size of the opening about identical as the part of transmittance section minimum.
The outer rim of shading piece is at least equal with the outer rim of transmittance section so that the light that luminescence component is sent out only appeared by the opening and
Specific keycap is projected through transmittance section.M381117 patents further disclose shading piece can be by lighttight thin-film material (example
Such as, polyester film) produced as sheets structure, then be attached at the bottom surface of transmittance section.Alternatively, shading piece is by lighttight ink
The bottom surface printed in a manner of printing as transmittance section is formed.Alternatively, in a manner of painting, lighttight spray painting is sprayed for shading piece
The bottom surface for being applied to transmittance section is formed.If however, on specific keycap and with define member/symbol transmission region, it is corresponding
Ground, the light that another luminescence component is sent out can set the transmission region to adopted member/symbol, at this time and according to No. M381117 specially
Keystoke structure disclosed in profit, disclosed light shield all can not effectively obstruct the light that two kinds of luminescence components are emitted with shading piece
Line.Also, the manufacturing yield of the shading piece of M381117 patent disclosures still has the space of promotion.
